Introduction: Proper interactions between uterus and conceptuses are necessary for establishment of pregnancy and implantation. Key factors in these regulations are prostaglandins (PGs). Recently we presented an important role of prostaglandin F2α (PGF2α) and its receptor (PTGFR) in porcine endometrium during early pregnancy. The aim of present study was to determine whether PGF2α can regulate the endometrial and embryonic expression of biglycan (BGN), metallopr...

Introduction: Prostaglandin F2α (PGF2α) is mainly known to be involved in luteolysis. However, our recent studies indicate that PGF2α synthesis and its receptor (PTGFR) expression are up-regulated in the porcine endometrium during embryo implantation. Aims of present study were: i) to immunolocalize PTGFR protein in uterus; ii) to elucidate the involvement of PGF2α-PTGFR signaling in angiogenesis in the porcine endometrium.Methods: Se...
